Abstract: A gas-measuring probe for determining a physical characteristic of a measuring gas, in particular the concentration of a gas component or the temperature or pressure of the measuring gas, which includes a sensor element accommodated in a housing, at least one connection cable for the sensor element having an electrical conductor, which is enclosed by an insulation sheath and contacts the sensor element, and a cable channel sealing the housing end, which has at least one axial cable feedthrough through which the connection cable is guided out of the housing. To achieve long-lasting sealing at the cable-exit end of the housing even at higher temperatures, the insulation sheath of the connection cable is at least regionally welded to the cable wall of the cable feedthrough. To this end, a tube made of a material that fuses with the insulation sheath and the cable channel when heated is slipped over the cable section of the connection cable lying inside the cable channel.

Abstract: A sensor unit for determining a physical sensor parameter of a measuring gas, in particular an oxygen concentration in an exhaust gas of an internal combustion engine is provided, which includes a sensor housing and at least one connection cable having an electrically insulating cable sheathing, for the transmission of energy and/or the sensor parameter, the sensor housing having at least one cable opening for the connection cable and at least one sealing element for sheathing and sealing the connection cable, the cable having better sealing than the related art and/or the ability to resist higher temperature loading. According to the invention, this is achieved by at least partially forming the sealing element as tube.
